Dear Paul, You ask:

You can see four here: https://www.flickr.com/photos/60409645@N05/sets/72157644179797609 These were taken before and after the crowds were around! I haven't seen the press photographs yet. As you can tell, the two rings look very much like those in the Douglas Hunt drawing that you use as your logo. They are square rather than round and have Roman numerals rather than Arabic but the two ranges seem to be the same, eg 7am to 6pm for the winter times. > I see that the GNU license states that > the author of the work must nevertheless > be attributed... I don't actually see that stated. The wording is: Attribution - You must attribute the work in the manner specified by the author or licensor... I do not see any specification by the author. Can you point me to this? While I would certainly cite Douglas Hunt myself, I see no formal requirement to do this. > In regards to the "Bill Gottesman stance", > it's an interesting concept, but it seems > to me that the narrow triangle of light > formed in this manner would be so short > as to preclude any kind of precision in the > reading of the time. Is this not correct? The triangle is certainly short but so is a compass needle and yet you can use such a needle to navigate a large boat. The triangle also has a pointed tip, again as a compass needle. Moreover, you also pay more attention to where your feet are. With practice, you can get good results using the Bill Gottesman stance. Take a look at: https://www.flickr.com/photos/60409645@N05/8901352415 I wasn't quite ready for the photograph to be taken but the narrow triangle actually points more precisely to the required hour point than is suggested by the shadow of my head. There is no substitute for a long stick held vertically in the correct place but you don't always have one to hand!
